An MPower search was performed at our institution for patients from 2014–2018 with keyword searches of “traumatic brain injury,” “TBI,” “diffuse axonal injury,” “DAI,” and “shear injury” based on radiological criteria. The aim of this study was to investigate the recovery of patients with pure DAI who remained in a coma for 6 hours or longer after brain injury. Results: Diffuse axonal injury (DAI) (OR 9.06, 95% CI 0.99 to 82.7) and frontal lobe injury of any type (OR 6.68, 95% CI 1.1 to 39.3) are independently predictive of … DAI is characterized by loss of consciousness at the time of the trauma, but the duration of coma is much longer than with concussion.

As the “diffuse” in the name implies, a diffuse axonal injury can cover a large area of the brain, as opposed to a focal injury, in which the damage is concentrated in one region.
